BOSS Brian Laws has hinted any further strengthening of his Scunthorpe United squad will come from loan deals.The January transfer window closes on Thursday but with finances tight, Laws is determined not to "waste" any money.The Iron have David Mirfin and Josh Walker coming back from injury, and though Christian Ribeiro and Damien Mozika are both currently sidelined, the manager is not prepared to pursue a player unless it is an "emergency"."I'm very mindful that if I use any amount of money that we have available, which would only be a small amount, and I use it and it's gone, then when we do need an emergency there's nothing," he said."That's the beauty of the loan system, at least we know we've got that until March."We'll work on it on a daily basis and see where we are. If we need to react, it might be a defender, it might be a midfield player, it might be a striker, it might be a wide man, we don't know."There's no point wasting the money. If there's an opportunity and we feel it's right to strengthen the team at that particular moment, then we'll do it."But if we want to release any more money it's got to come via a player going out."At the moment, that seems unlikely to happen with no bids forthcoming."There's nothing there, and I'm delighted, particularly if we're talking about Mark Duffy," Laws added. "I'm delighted about the fact Duffy's not attracting any attention."We want him here because he's going to be an integral part in our survival this year."I'll be very surprised (if anyone goes)."I'm saying no, but whilst it's a no now, there are still a few days left of the window."United will make a decision today whether to offer full-back Eddie Nolan a deal. The topic was due to be discussed at a board meeting last week, but that has been put back to today."We're discussing Eddie's situation with us," Laws explained."He's a player everybody knows about. He can support the back four and that's an area where, particularly the wide areas and right-back, we haven't got a lot of cover there."Can we do anything? I don't know."We've got a board meeting today because Thursday's was cancelled."We'll discuss that at length, I'm sure; it will be one of the topics."We'll have to wait and see."
